The National Consortium for Assessing Drug Control
Initiatives, funded by the Bureau of Justice Assistance and
coordinated by the Criminal Justice Statistics Association, collected
drug offender processing data from eight states: Alaska, California,
Iowa, Minnesota, Nebraska, New York, North Carolina, and Virginia. The
purpose of the project was to track adult drug offenders from the
point of entry into the criminal justice system (typically by arrest)
through final court disposition, regardless of whether the offender
was released without trial, acquitted, or convicted. These data allow
researchers to examine how the criminal justice system processes drug
offenders, to measure the changing volume of drug offenders moving
through the different segments of the criminal justice system, to
calculate processing time intervals between major decision-making
events, and to assess the changing structure of the drug offender
population. For purposes of this project, a drug offender was defined
as any person who had been charged with a felony drug offense. The
data are structured into six segments pertaining to (1) record
identification, (2) the offender (date of birth, sex, race, ethnic
origin), (3) arrest information (date of arrest, age at arrest, arrest
charge code), (4) prosecution information (filed offense code and
level, prosecution disposition and date), (5) court disposition
information (disposition offense and level, court disposition, final
disposition date, final pleading, type of trial), and (6) sentencing
information (sentence and sentence date, sentence minimum and
maximum). Also included are elapsed time variables. The unit of
analysis is the felony drug offender.
